What it is
The Glow-worm 2000800089 is a mechanical timer supplied as a replacement time control for Glow-worm boilers. It switches the appliance's heating and hot water periods on and off according to the segments or pins set on the dial. Being a mechanical unit, it is driven from the boiler's own supply rather than a separate electronic programmer.
Signs this part needs replacing
- The boiler runs continuously and ignores the set on and off periods
- The dial fails to advance, or stalls part way round its cycle
- Heating or hot water does not come on at the programmed time
- The dial is stiff to turn or the timer body feels loose in its housing
- Switching becomes intermittent and no longer matches the set programme
Before you order
- Match the number on the existing timer against GLOWWORM2000800089
- Check the boiler model and serial number on the appliance data badge
- Confirm how the timer is mounted on your appliance, as an integral control or a plug-in unit
- Isolate the boiler electrically before removing or refitting the timer
